reverseing valve need help installing

Can anyone of you guys please help me out i installed a reverseing valve on a trane split heat pump it was very difficult to weld in the vavle was very close to the outdoor coil just want to know if anyone has a easier technique and would be willing to share the knowledge i would be very thankful

My suggestion to installing a RV, use Stay-Brite 5% silver solder. It melts at 436°F, always try and point the flame away from the valve body, wrap the body with wet cloth, do one tube at a time then cool it off, if you try and do all of them you'll cook the valve.

we all have our own opinions on how to do things, but that's what I do and it work for me

I have found that sometimes it is easier to cut the old valve out and braze stubs in outside of the unit also. However this does bring up an interesting question; What do you guys use to braze reversing valves? I have always used Sil-Fos but I can"t help but wonder if there"s not something better?

see post #2, Stray-Brite melts at 430°F and has the same tensile strength as braze, the issue is the price. One pound costs a small fortune and you must use there flux.

Never do it yourself

Reversing valves are for helpers. Make him do it and then cuss him out real good when it leaks. Your helper will feel like crap and develop self esteem issues but you'll feel superior.

Of course I'm just kidding. RV's can be (and usually are) a royal PITA. I have used 15% with success on both R22 and R410 systems but the liquidus temp is 1465F so you have to get it hot. Use an oxy/acetylene rig and hit it quick and clean. You should not have to have your torch on the tube for more than 15 seconds or so. Wrap the valve with strips of dripping wet cloth and do the tubes one at a time.

jmac00 are you sure you're not referring to Stay-Silv 5% as opposed to Stay-Brite 8% ??? The Harris website doesn't list a Stay-Brite 5% but does list 8% with 430F liquidus

The picture in my avatar is of the Houston Ship Channel and was taken from my backyard. I like to sit outside and slap mosquitos while watching countless supertankers, barges and cargo ships of every shape and size carry all sorts of deadly toxins to and fro. It's really beautiful at times.....just don't eat the three eyed fish....
